8 Maintenance and fault rectification

8.1 Maintenance

If the instrument is used properly, no special maintenance is required
in normal operation.

8.2 Remove interferences

The operator of the system is responsible for taking suitable measures
to rectify faults.

VEGAFLEX

67 offers maximum reliability. Nevertheless, faults can

occur during operation. These may be caused by the following, e.g.:

l

Sensor

l

Process

l

Voltage supply

l

Signal processing

The first measures to be taken are to check the output signals as well
as to evaluate the error messages via the indicating and adjustment
module. The procedure is described below. Further comprehensive
diagnostics can be carried out on a PC with the software PACTware
and the suitable DTM. In many cases, the causes can be determined
and the faults rectified this way.

Should these measures not be successful, please call in urgent cases
the VEGA service hotline under the phone no. +49 1805 858550.

The hotline is available to you 7 days a week round-the-clock. Since
we offer this service world-wide, the support is only available in the
